The CPVC True Union Diaphragm Valve (also known as membrane valves) is ideal for more complex commercial or industrial applications. It uses a diaphragm (EPDM/FPM or PTFE) to control the flow, offering excellent resistance to chemicals, moisture, and high temperatures. The durable CPVC material is enhanced with BASF anti-UV and antioxidant additives, improving weather resistance, aging resistance, and overall service life.

This valve is available in sizes from ½" to 4", with spigot type, socket ends, and flange connections.
